Why are you trying to insinuate these owners are of harm to the usa or on the ofac list?

I don't think that was contemplated in the facts the original poster laid out (but I might have missed that - I haven't had time to read all the posts).Let me just leave you with this thought - there are literally hundreds if not thousands of things a PM can do that might be argued by an owner as causing them financial harm.  

Your problem is that you're writing "nice notes" instead of adhering to the lease agreement.Smoking of any substance - legal or illegal - is not allowed in the rental.

You will need to make sure you have all i's dotted and t's crossed to effect an actual sale.This may be viewed as aggressive by some and just normal by others but depending on how it is set up and how the transaction is handled will determine the substance over form issue with the IRS.

If this is really a bad person, they could do you some physical harm, or worse!

Bad and good areas can be radically different in different countries, too (and with today's technology and ease of business transactions, the world's your oyster) - a bad neighbourhood in Japan means factory and shift workers, blue collar folk who, aside from potentially being a few weeks late in payment, would never trash or harm a property, or even cause their neighbours to complain about anything.In the US - different story altogether.

NOT UNDER THE INFLUENCE: I am not now under the influence of alcohol or any other mind-altering substance, nor am I taking medication that would cloud my judgment or make me unable to think clearly. ________ 20.

I tell our tenants at the onset that I value open and honest communication and if they choose to lie to me at anytime about anything, it would seriously harm our relationship.

If so, what was the controlled substance?

You have no rights at all from the position of holding any tax lien to possession or in taking the fruits of ownership.Seems you mentioned the business model offering "privacy" most thieves usually don't want to make known their escapades, perhaps a money laundering scheme might keep the rents paid under wraps too, but I don't see anything addressing the privacy side nor can it be to the point that this method can't be discovered.Well, again, I spent time addressing guru type matters keeping newbies out of harm's way.
